Description

The TS3702 is a micropower CMOS dual voltage comparator with extremely low consumption of 9μA typ / comparator (20 times less than bipolar LM393). The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual open- collector output comparators. Thus response times remain similar to the LM393.

Table 1. Absolute maximum ratings

  1. All voltage values, except differential voltage, are with respect to network ground terminal.
  2. Differential voltages are the non-inverting input termi nal with respect to the inverting input terminal.
  3. The magnitude of the input and the output voltages must never exceed the magnitude of the positive and
  4. P d is calculated with Tamb = +25°C, Tj = +150°C and
  5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a

while the other pins are floating.

  1. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between

connected pin combinations while the other pins are floating.

  1. Charged device model: all pins and the package are charged together to the specified voltage and then

discharged directly to the ground through only one pin. This is done for all pins. Table 2. Operating conditions
